Comparative Study on Seismic Behaviour of Rc and Composite Structure for Different Types of Irregularities

Abstract

When compared to composite structures for high rise construction, RC structures have increased seismic weights. The structural design influences how multi-storey buildings react to earthquakes. In the case of vertical constructions, composite structures provide a distinctive option of ergonomic member and material design. In the majority of developing nations, reinforced concrete structures are the preferred construction technique. A combined structural property of concrete and steel is achieved by using composite structures. In the current work, ETABS is used to model and analyse the comparison of RC and composite structures with CFT columns for different kinds of irregularities, such as vertical geometric irregularity, mass irregularity, and stiffness irregularity, in accordance with IS codes. When RC constructions are compared to composite structures, it has been found that storey displacements and drifts are considerably fewer in RC structures. The base shear for the composite structure is lower than that of the RC structure due to the composite structure’s lighter weight.
